I am asking of anyone here has any information on mold and sarcoidosis?

Or neurosarcoidosis.

And indoor mold or indoor bacteria, as might be endemic in a damp, frequently leaking building.

Sarcoidosis seems to show up in the news when it appears in clusters. For example, there is a building in Vermont where SIX employees got it and the odds against that happening randomly are millions to one..

It can kill people, and five percent of the people who get it die of it, according to one paper I saw. Another said that 37% of the people who got it eventually died of this disease.

The nodules can appear i the brain or the heart, liver, kidneys, spine, etc. Its 'caused by an unknown toxin' or 'unknown agent'.
